We currently have 4 offices, 2 in the Pittsburgh area and 2 in California (one is Saratoga and one being built in San Fran). The plan is to connect each one through a dedicated T1 line for redundancy and VOIP and video conferencing purposes. I was planning on installing 3548 XL switches in all of the offices (the San Fran office and one of the Pittsburgh offices will have close to 100 people while the other two offices will have around 30 people). The corporate offices will use the other two offices for Internet access. The questions I have are as follows: * What type of router should be placed in the offices? I was thinking 1720 for the small corporate offices and the 3640 for the two larger offices as I believe this will provide us with the performance we need for VOIP and video conferencing over IP * Are the 3548 XL switches good enough? I read a recent review in Network World that said QOS is lacking in the 3548 XL switch Thanks, Jeff ___________________________________ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
